Tetralogy of Fallot with subarterial ventricular septal defect: Surgical outcome in the current era.

Background: Tetralogy of Fallot (TOF) with subarterial ventricular septal defect (VSD) is more common among Asians than Caucasians. Compared with the regular subaortic VSD postoperative right ventricular outflow obstruction is more common because of the sub-pulmonary extension of the defect. The objective of this study is to analyze the surgical implications and outcomes of patients with TOF - subarterial VSD in the current era.

Treatment of sporadic inclusion body myositis with bimagrumab.

Objective: To study activin signaling and its blockade in sporadic inclusion body myositis (sIBM) through translational studies and a randomized controlled trial.

Methods: We measured transforming growth factor β signaling by SMAD2/3 phosphorylation in muscle biopsies of 50 patients with neuromuscular disease (17 with sIBM). We tested inhibition of activin receptors IIA and IIB (ActRII) in 14 patients with sIBM using one dose of bimagrumab (n = 11) or placebo (n = 3).

Preliminary evaluation of a microtransesophageal probe in neonates and young infants undergoing surgery for congenital heart disease.

Background: The larger size of the currently available transesophageal echocardiography (TEE) probes limits their use to relatively older infants undergoing cardiac surgery. In very young neonates and infants, epicardial echocardiogram is used to assess postoperative residual defects. Recently, a miniaturized microTEE probe compatible in neonates has been introduced for clinical use.

Conventional repair of the double-outlet left ventricle involves a complex intraventricular tunnel, extracardiac conduit, or the pulmonary artery translocation operation. We report an arterial switch operation and closure of ventricular septal defect for anatomic correction of this anomaly.

Spectral investigation and characterization of host-guest inclusion complex of 4,4'-methylene-bis(2-chloroaniline) with beta-cyclodextrin.

The host-guest inclusion complex of 4,4'-methylene-bis(2-chloroaniline) (MBCA) with beta-cyclodextrin (β-CD) was prepared by co-precipitation method and characterized using absorption, fluorescence, fourier transform infrared, differential scanning calorimetry, scanning electron microscopy, atomic force microscopy and X-ray diffraction. The spectral shifts revealed that the aniline ring of 4,4'-methylene-bis(2-chloroaniline) was entrapped in the beta-cyclodextrin cavity. Nano second time resolved fluorescence studies revealed that 4,4'-methylene-bis(2-chloroaniline) exhibits single exponential decay in aqueous medium and bi-exponential in beta-cyclodextrin medium confirmed the formation of 1:1 inclusion complex.

2,6-Dinitroaniline and β-cyclodextrin inclusion complex properties studied by different analytical methods.

The formation of supramolecular host-guest inclusion complex of 2,6-Dinitroaniline (2,6-DNA) with nano-hydrophobic cavity of β-cyclodextrin (β-CD) in solution phase were studied by UV-visible spectrophotometer and electrochemical method (cyclic voltammetry, CV). The prototropic behaviors of 2,6-DNA with and without β-CD and the ground state acidity constant (pKa) of host-guest inclusion complex (2,6-DNA-β-CD) was studied by Spectrophotometrically. The binding constant of inclusion complex at 303 K was calculated using Benesi-Hildebrand plot and thermodynamic parameter (ΔG) were also calculated.

Surface display of roGFP for monitoring redox status of extracellular microenvironments in Shewanella oneidensis biofilms.

Biofilms are the most ubiquitous and resilient form of microbial life on earth. One most important feature of a biofilm is the presence of a self-produced matrix, which creates highly heterogeneous and dynamic microenvironments within biofilms. Redox status in biofilm microenvironments plays a critical role in biofilm development and function.

Production of α-amylase for the biosynthesis of gold nanoparticles using Streptomyces sp. MBRC-82.

Marine actinobacterial synthesis of gold nanoparticles has good potential to develop simple, cost-effective and eco-friendly methods for production of important biomaterials. In this context, gold nanoparticles have attracted considerable attention in recent years, owing to their various applications. In this paper, we report on the production of α-amylase for the extracellular synthesis of gold nanoparticles using Streptomyces sp.

Membrane permeabilization underlies the enhancement of extracellular bioactivity in Shewanella oneidensis by a membrane-spanning conjugated oligoelectrolyte.

A stilbene-based membrane spanning conjugated oligoelectrolyte 4,4'-bis(4'-N,N-bis(6"-(N,N,N-trimethyl ammonium) hexyl) amino)-styryl) stilbene tetraiodide (DSSN+) has been reported to be able to interact with bacterial cells and enhance their bioelectricity generation in bioelectrochemical devices, although the mechanism remains elusive. The goal of this study was to elucidate the impacts of DSSN+ on extracellular bioactivity and the underlying mechanism. Specifically, extracellular ferrihydrite reduction by Shewanella oneidensis was used to evaluate the influence of cell-DSSN+ interaction.

Circular shunt in a pulmonary artery to right atrial tunnel, an anomaly unreported so far.

While aortico-right atrial tunnels with left to right shunt from aorta to right atrium are reported widely, pulmonary artery to right atrial tunnels have not been described so far. Such a tunnel will lead to a circular shunt with a recirculation of blood in the right sided cardiac chambers repeatedly bypassing the pulmonary capillary bed. This newly described pulmonary artery to right atrial tunnel was closed nonsurgically with a duct occluder after angiographic delineation.

Giant coronary artery aneurysms in a 58-year-old.

All giant Kawasaki aneurysms may not regress fully; some may eventually calcify, undergo thrombosis, and get detected in asymptomatic adults at later age. Tomisaku Kawasaki initially described this illness as mucocutaneous lymph node syndrome in childhood in 1967 and coronary arteritis was recognized later. We present a 58-year-old male, possibly one of the oldest surviving patients with giant coronary aneurysms who presented with large secundum atrial septal defect (ASD) with heart failure.

Elevated soluble CD163 in gestational diabetes mellitus: secretion from human placenta and adipose tissue.

Recently soluble CD163 (sCD163), a cleaved form of the macrophage receptor CD163, was identified as a macrophage-specific risk-predictor for developing Type 2 Diabetes. Here, we investigate circulating levels of sCD163 in gestational diabetes mellitus (GDM). Furthermore, given the role of the placenta in the pathogenesis of GDM, we assessed placental contribution to sCD163 secretion.

Marine actinobacteria: an important source of bioactive natural products.

Marine environment is largely an untapped source for deriving actinobacteria, having potential to produce novel, bioactive natural products. Actinobacteria are the prolific producers of pharmaceutically active secondary metabolites, accounting for about 70% of the naturally derived compounds that are currently in clinical use. Among the various actinobacterial genera, Actinomadura, Actinoplanes, Amycolatopsis, Marinispora, Micromonospora, Nocardiopsis, Saccharopolyspora, Salinispora, Streptomyces and Verrucosispora are the major potential producers of commercially important bioactive natural products.

Environmental contamination of drinking water with chromium (Cr) has been increasing in more than 30 cities in the United States. Previous studies from our group have shown that Cr affects reproductive functions in female Sprague Dawley rats. Although it is impossible to completely remove Cr from the drinking water, it is imperative to develop effective intervention strategies to inhibit Cr-induced deleterious health effects.

Heuristics for multiobjective optimization of two-sided assembly line systems.
